Can you put 1978 brake calipers on a 1975 GL1000? I noticed a couple of differences between the two, on the 1978 the pistons are shorter and the caliper itself is one piece instead of two. I'm not sure if that is a problem or not.

If I remember , the callipers will interchange on the calliper brackets but the brackets are totally different. The pistons are the same length but different diameters.The 78 discs are thinner than the 75-77 ones; might give a problem once they wear down but I doubt it. I'll check the interchange in the morning.

'Impossible' is just a level of difficulty!The only stupid question is the one you didn't ask first!

Edit Tuesday 8th; Can't even read my own chart ! Damned old age, mixed with stupidity ! Real good combo! http://www.wingovations.com/#/stainless ... 4548580412
Both of them have pistons with the same diameter and the same length, although they are different. Did a quick measure up (but didn't have time to actually swap anything over) and I'm pretty certain that they interchange.
